Antirrhinum plant named ‘Balumrest’

ABSTRACT

A new and distinct cultivar of Antirrhinum plant named ‘Balumrest’, characterized by its upright, outwardly spreading and mounded plant habit; freely basal branching growth habit; and dark red and yellow-colored flowers.

Botanical classification/cultivar designation: Antirrhinum majus cultivar Balumrest.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Antirrhinum plant, botanically known as Antirrhinum majus, and hereinafter referred to by the name ‘Balumrest’.

The new Antirrhinum is a product of a planned breeding program conducted by the Inventor in Arroyo Grande, Calif. The objective of the breeding program is to develop new vigorous Antirrhinum cultivars that have a freely basal branching growth habit and numerous flowers with attractive coloration.

The new Antirrhinum originated from a self-pollination made by the Inventor in 2000 of a proprietary Antirrhinum majus selection identified as code number 59, not patented. The cultivar Balumrest was discovered and selected by the Inventor as a flowering plant within the progeny of the stated self-pollination in a controlled environment in Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by cuttings taken in Arroyo Grande, Calif. since May, 2000, has shown that the unique features of this new Antirrhinum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Balumrest’. These characteristics in combination distinguish ‘Balumrest’ as a new and distinct Antirrhinum cultivar:

1. Upright, outwardly spreading and mounded plant habit.

2. Freely branching growth habit.

3. Dark red and yellow-colored flowers.

Compared to plants of the parent selection, plants of the new Antirrhinum are more upright and differ in flower coloration.

Plants of the new Antirrhinum can be compared to plants of the cultivar Balumbreo, disclosed in U.S. Plant patent application Ser. No. 10/109,509. In side-by-side comparisons conducted in West Chicago, Ill., plants of the new Antirrhinum differed from plants of the cultivar Balumbreo in the following characteristics:

1. Plants of the new Antirrhinum were more compact than plants of the cultivar Balumbreo.

2. Plants of the new Antirrhinum had smaller leaves than plants of the cultivar Balumbreo.

3. Plants of the new Antirrhinum had more flowering branches per plant than plants of the cultivar Balumbreo.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Antirrhinum, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Antirrhinum.

The photograph on the first sheet comprises a side perspective view of a flowering plant of ‘Balumrest’.

The photograph on the second sheet comprises a close-up view of typical flowers of ‘Balumrest’.

DETAILED BOTANICAL DESCRIPTION

The cultivar Balumrest has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The aforementioned photographs and following observations and measurements describe plants grown in West Chicago, Ill., under commercial practice in a polycarbonate-covered greenhouse with day temperatures ranging from 18 to 24° C., night temperatures ranging from 10 to 13° C. and light levels ranging from 4,000 to 7,000 footcandles. Rooted young plants were planted in 10-cm containers and had been growing for about 14 weeks when the photographs and the description were taken.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
